0024884: expand the list of short compiler names in CMake meta-project

List of compiler short names expanded (added: gcc, gxx, mingw, clang, intel); generation of install folder name is corrected to include compiler name without spaces even if short name is not recognized.

Tcl search was fixed (tcl8.6 has higher priority than tcl or tcl8.5);
Search for fb2build.h of freetype 2.5.1 was corrected

THRDPARTY_PATH is included into LD_LIBRARY_PATH
