Summary: trycompile does not work on MSVC_IDE with
--debug-trycompile
Description:
I've written a small CMakeLists.txt (attached), which demonstrates the
problem that the result of the second try_compile attempt (e.g. by
CHECK_FUNCTION_EXISTS) has the same result as before and this causes
try_compile to produce wrong results.
Since the CMake temporary project files are not deleted before the next
try_compile command, the MSVC assume that the output file is still
up-to-date. This could be workarounded if a additional dependency for the
output file to the generated project file is introduced (don't know if this
is possible.
