0015673: CMAKE_C_COMPILER is used to link a CXX shared library on Solaris
and may be removed when cmake is updated to version 3.4 or later.

Linking C++ libraries with the C compiler is not needed; it causes the compiler
driver to not include libraries that need to be linked to the resulting
library (such as libstdc++ in the case of gcc).

The second set of lines removed by this patch will be submitted upstream.
It removes use of historical directories which are no longer used.
Any version of Studio from the last five years should automatically set
the correct paths.
