Does anyone have experience getting CMake to work with the PGI compilers? I'd like to try building Manta with it, but I can't even get a simple project to configure correctly with it (see below). It's obviously just a problem with the flags used during the TryCompileTest, but I haven't been able to find out how to change the flags that CMake uses during those tests.

Any thoughts?

Thanks,

I "think" you can manually force "CXX=..." and "CC=..." _after_ the compiler test has been run. I do have a cmake file in which I use a compiler for a theoretical architecture that does not yet exist and whose generated bycode would most likely not be executable on the host machine ... and it works.

I think I have something like

SET(USE_MY_COMPILER YES CACHE BOOL "bla");
IF (USE_MY_COMPILER)
  SET(CMAKE_CXX_COMPILER,"blubba");
  ....
ELSE(....)
...
ENDIF(...)

I "think" cmake then uses the CC/CXX environment variables for the compiler test script; at least it works in my case.

Cheers,

Ingo

PS: I'm pretty sure it uses CMAKE_C_FLAGS/CMAKE_CXX_FLAGS during compilation. I set these, too, so maybe that's the difference.
