[CMake] A question about cache variables
Hi All, I have a problem with cache variables in cmake. I want to check the combiler for a certain flag -C99 flag. So, I used the following statement CHECK_C_COMPILER_FLAG(-C99 FLAG_OK) The problem is that we I ran cmake for the first time it said that c99 is not found and set the FLAG_OK variable in CMakeCache.txt to 0. Now, I fixed the problem =in the compiler to make it support -C99. But cmake doesnot check the flag any more and just keep saying not found. This is becuase the FLAG_OK is already equals to 0 in cache file. Is there any way to delete the cahce variable. or force cmake to check for the flag every time I run it?

Rerun CMake with -UFLAG_OK or restart from within an empty build directory or use UNSET(FLAG_OK CACHE) in your CMakeLists.txt, but note: The purpose of caching is to avoid finding out the concerned variables' values every time CMake runs, and the capabilities of a compiler w.r.t. the acceptance of flags usually don't change often.
