 The cmake based buildsystem for expat works on Windows (cygwin, mingw, Visual 

 Studio) and should work on all other platform cmake supports.

 

-Assuming ~/expat-2.2.6 is the source directory of expat, add a subdirectory

+Assuming ~/expat-2.2.7 is the source directory of expat, add a subdirectory

 build and change into that directory:

-~/expat-2.2.6$ mkdir build && cd build

-~/expat-2.2.6/build$

+~/expat-2.2.7$ mkdir build && cd build

+~/expat-2.2.7/build$

 

 From that directory, call cmake first, then call make, make test and 

 make install in the usual way:

-~/expat-2.2.6/build$ cmake ..

+~/expat-2.2.7/build$ cmake ..

 -- The C compiler identification is GNU

 -- The CXX compiler identification is GNU

 ....

 -- Configuring done

 -- Generating done

--- Build files have been written to: /home/patrick/expat-2.2.6/build

+-- Build files have been written to: /home/patrick/expat-2.2.7/build

 

 If you want to specify the install location for your files, append 

 -DCMAKE_INSTALL_PREFIX=/your/install/path to the cmake call.

 

-~/expat-2.2.6/build$ make && make test && make install

+~/expat-2.2.7/build$ make && make test && make install

+Release 2.2.7 Wed June 19 2019
+        Security fixes:
+       #186 #262  Fix extraction of namespace prefixes from XML names;
+                    XML names with multiple colons could end up in the
+                    wrong namespace, and take a high amount of RAM and CPU
+                    resources while processing, opening the door to
+                    use for denial-of-service attacks
+
+        Other changes:
+       #195 #197  Autotools/CMake: Utilize -fvisibility=hidden to stop
+                    exporting non-API symbols
+            #227  Autotools: Add --without-examples and --without-tests
+            #228  Autotools: Modernize configure.ac
+       #245 #246  Autotools: Fix check for -fvisibility=hidden for Clang
+       #247 #248  Autotools: Fix compilation for lack of docbook2x-man
+       #236 #258  Autotools: Produce .tar.{gz,lz,xz} release archives
+            #212  CMake: Make libdir of pkgconfig expat.pc support multilib
+       #158 #263  CMake: Build man page in PROJECT_BINARY_DIR not _SOURCE_DIR
+            #219  Remove fallback to bcopy, assume that memmove(3) exists
+            #257  Use portable "/usr/bin/env bash" shebang (e.g. for OpenBSD)
+            #243  Windows: Fix syntax of .def module definition files
+                  Version info bumped from 7:8:6 to 7:9:6

+#   AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   For every FLAG1, FLAG2 it is checked whether the compiler works with the
+#   flag.  If it does, the flag is added FLAGS-VARIABLE
+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+#   CFLAGS) is used.  During the check the flag is always added to the
+#   current language's flags.
+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
+#
+#   NOTE: This macro depends on the AX_APPEND_FLAG and
+#   AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
+#   AX_APPEND_LINK_FLAGS.

+#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space

+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.

+#   AX_REQUIRE_DEFINED(MACRO)
+#
+# DESCRIPTION
+#
+#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
+#   been defined and thus are available for use.  This avoids random issues
+#   where a macro isn't expanded.  Instead the configure script emits a
+#   non-fatal:
+#
+#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
+#
+#   It's like AC_REQUIRE except it doesn't expand the required macro.
+#
+#   Here's an example:

+#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
