find_package(foo) does not create cache entry for foo_DIR
Let's say you have:
find_package(foo)and you call CMake with -Dfoo_DIR=/path/to/foo. Later on, you run ccmake to try to remember where foo_DIR is... but foo_DIR does not show up in the menu. You have to manually edit CMakeCache.txt to find foo_DIR. This is confusing. Is there any way this can be fixed? Perhaps find_package() can change the type of foo_DIR to PATH?
