[CMake] Where to change default link line on Cmake

Yes.

hpci6001t(salmr0)133:ccmake -version
ccmake version 2.8.1

Correct nothing left from any in-source builds.

OK. Good to know.

Ahhh.. That is the problem cmake is not detecting the correct compiler ID.

hpci6001t(salmr0)139:rm -rf build/
hpci6001t(salmr0)140:mkdir build
hpci6001t(salmr0)141:cd build
/gpfs01/vol0/salmr0/mspain/fd/build
hpci6001t(salmr0)142:cmake ..

I guess I need to INCLUDE or something the:

Modules/CMakeDetermineCompilerId.cmake

File in my CMakeLists.txt file? Also I put in some message like this one:
message(STATUS "CMAKE_MODULE_PATH = ${CMAKE_MODULE_PATH}")

And as you can tell from the output above It looks like cmake does not know
the CMAKE_MODULE_PATH. Should that have been set or is that something Every
user should have to put in their CMAKE_MODULE_PATH file?

Thanks
