[CMake] TRY_LINK and CheckCXXSourceLinks ??

[Marcel Loose]

Hi David,

I guess you're right. Further playing with CheckCXXSourceCompiles and
investigating the generated CMakeLists.txt file led me to the conclusion
that the link step is indeed also performed. I was led astray by the
name of the command and my notion that it wraps TRY_COMPILE. Also my
background in the GNU Autotools, which has TRY_COMPILE, TRY_LINK and
TRY_RUN, didn't really help. Sorry for the noise.

Best regards,
Marcel Loose.

Doesn't CheckCXXSourceCompiles link?

I think there's no way to avoid the link in a try_compile...
