Building expat for nomacs

You will need expat to build exiv2 which is required for building nomacs.

• Open CMake GUI
• Point where is the source to this directory
• Choose a build folder (e.g. expat/build2017-x64)
• Hit Configure then Generate
• Uncheck BUILD_examples and BUILD_tests
• Batch build all projects (2 failed and 8 succeeded is fine)
• You should now have an expat.dll in $YOUR_EXPAT_BUILD_PATH$/Release
• In the CMakeUserPaths.cmake of your exiv2 project, add these paths:

SET(EXPAT_INCLUDE_DIR "$EXPAT_PATH$/lib")
SET(EXPAT_BUILD_PATH "$EXPAT_BUILD_PATH$")
