[CMake] can't configure GTEST_ROOT with ccmake or cmake-gui

[Witold Eryk Wolski]

Hi,

would like to start using gtest with a project. I use cmake to configure 
the project.

So I was pleased to see that :
cmake 2.8 ships with an FindCTest.cmake file. 

However FindCTest.cmake expects me either to set en env variable CTEST_ROOT 
or pass it as an cmake  ariable (I guess with -DCTEST_ROOT ?)

However, the convention I have so far is that all dependencies can be 
configured using ccmake or cmake-gui.
Therefore, I would like to do the same with gtest. However, can't find a 
way to set GTEST_ROOT with ccmake or cmake-gui.

Can I add anything, and exactly what, to my CMakeLists.txt file so that 
CTEST_ROOT will show up in ccmake in order to be set properly?


regards
Witold
