cmake: support for building git on windows with mingw
This patch facilitates building git on Windows with CMake using MinGW NOTE: The funtions unsetenv and hstrerror are not checked in Windows builds. Reasons NO_UNSETENV is not compatible with Windows builds. lines 262-264 compat/mingw.h compat/mingw.h(line 25) provides a definition of hstrerror which conflicts with the definition provided in git-compat-util.h(lines 733-736). To use CMake on Windows with MinGW do this: cmake `relative-path-to-srcdir` -G "MinGW Makefiles" Signed-off-by: Sibi Siddharthan <sibisiddharthan.github@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
