Noted in 5.5.32, 5.6.12, 5.7.2 changelogs. The CMake check for unsigned time_t failed on all platforms.
Description: Toplevel configure.cmake contains new system check # check whether time_t is unsigned CHECK_C_SOURCE_COMPILES(" int main() { int array[(((time_t)-1) > 0) ? 1 : -1]; return 0; }" TIME_T_UNSIGNED) This check will fail not because time_t is signed (which is the case on Windows), but because <time.h> which includes typedef for time_t is not included. How to repeat: Open CMakeFiles/CMakeError.log Find "Performing C SOURCE FILE Test TIME_T_UNSIGNED failed with the following output:" ... src.c(4): error C2065: 'time_t' : undeclared identifier [H:\bzr\tpms1\xxx\CMakeFiles\CMakeTmp\cmTryCompileExec.vcxproj] Suggested fix: For example, add #include <time.h> to the start of the source snippet CMAKE_EXTRA_INCLUDE_FILES should work as well (configure.cmake uses it in some places)
