Provide similar to gtest-config functionality for FindGTest.cmake module

[GoogleCodeExporter]

Some features of gtest-config missing in FindGTest.cmake module. Specifically 
`gtest-config 
--ldflags` and `gtest-config --libs` functionality required to link tests 
properly. After upgrading 
to gtest-1.5 from gtest-1.4 I had problems with missing -lpthread on linking 
stage. Maybe I 
can use
 execute_process (COMMAND gtest-config --libs OUTPUT_VARIABLE GTest_ld_flags   
OUTPUT_STRIP_TRAILING_WHITESPACE)
to solve this issue, but it seems that I'll lose portability.
Could you please add   GTest_CXX_FLAGS, GTest_LD_FLAGS, GTest_LIBS to 
FindGTest module?

What system are you using Google Test on? What are the commands you use and 
what are the error messages?

Note that we do not write FindGTest.cmake; you should contact CMake authors 
about it.

Yes, I know that target_link_libraries (prgnm-test  gtest pthreads) works fine.

Oops, target_link_libraries (prgnm-test  gtest pthread) of course.

If you use CMake, the best way to handle this is to add 

add_subdirectory(<path_to_gtest_root>)

before you use the gtest library in your CMake script.

Closing, as we don't maintain FindGTest.cmake.
