[CMake] Continued issues in trying to get CMake working on OpenVMS

[Custin, Jay (CSC Sw Middleware)]

So I ran into a few minor issues compiling/linking the CMake images (compiler threw a few "warnings" which didn't really prove significant so I simply "silenced" the warnings to enable the code to compile clean and link).  I accomplished this with the following:

bash$ export CFLAGS="-Wc/warnings=disable=all"
bash$ export CXXFLAGS="-Wc/warnings=disable=all"
bash$ ./configure

The bootstrap "happily" compiles and links ALL the code without any issues... but then CMake does some self-evaluation and things get very ugly... very fast.  For whatever reason the bootstrap has no issues "finding" the various C/C++ header files to compile and link the CMake source... but when the "interim" CMake itself then tries to find them... complete and utter failure.

At present I have what I would call the "interim" version of CMake built (which at this phase requires adding the option -DCMAKE_BOOTSTRAP=1 on the end of the cmake command to do much of anything).  I have included an abbreviated version of this build below:

bash$ export CFLAGS="-Wc/warnings=disable=all"
bash$ export CXXFLAGS="-Wc/warnings=disable=all"
bash$ ./configure --system-curl --system-zlib --verbose --init=BuildCMakeOpenVMS_CacheFlags.cmake

On and on it goes.

This gets made even more frustrating in that it appears that the testing phase does a VERY good job cleaning up after itself... I had to go in to the files, insert a series of MESSAGE statements to display the code it would try to build, then manually generate one of the files which it said failed to compile... but then I could manually compile and link from the very same Bash shell without any issue.

So the very headers that the configure/bootstrap used to compile and link the CMake images... it then can't find when it RUNS its tests using those same images.  I figure that it MAY have something to do with something like the following:

Modules/CheckIncludeFile.cmake
Modules/ CheckIncludeFileCXX.cmake

Anyone have any suggestions?  

Any ideas on how to get how to get the partially built image (the initial image that requires passing -DCMAKE_BOOTSTRAP=1 to run) to NOT clean up after itself?  I figure this might help me discern where things have got haywire.
