Failure on cross-compiling for Windows using mingw #609
Description
Describe the bug
Over at JuliaPackaging/Yggdrasil#9453 I try to cross-compile MEOS for different platforms for the Julia programming language. When cross-compiling for Windows (using mingw), this fails:
[ 43%] Building C object meos/postgres/port/CMakeFiles/port.dir/pg_bitutils.c.obj

To Reproduce
Steps to reproduce the behavior:
The Julia recipe is here, but in short this is using a mingw toolchain and the following statements using the 1.2.0 rc1 release using a git checkout.
cd $WORKSPACE/srcdir/MobilityDB
cmake -B build -DCMAKE_INSTALL_PREFIX=${prefix} -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TARGET_TOOLCHAIN} -DCMAKE_BUILD_TYPE=Release -DMEOS=ON -DHAVE_X86_64_POPCNTQ_EXITCODE="FAILED_TO_RUN" -DHAVE_X86_64_POPCNTQ_EXITCODE__TRYRUN_OUTPUT=
cmake --build buildNote I needed to set DHAVE_X86_64_POPCNTQ cache variables because the TRY_RUN cmake is not supported in cross-compilation mode. While related to the failed portion of code, setting the exit code to either zero or one does not make a difference.
Apart from many warnings (overflows) the rest of the codebase seems to cross-compile fine.
