Test try_compile project mode The try_compile command project mode builds an entire source tree instead of one source file. It uses an existing CMakeLists.txt file in the given source tree instead of generating one. This commit creates a test for the mode in the TryCompile test.

Fix recursive try_compile calls When building an entire source tree with try_compile instead of just a single source file, it is possible that the CMakeLists.txt file in the try-compiled project invokes try_compile. This commit fixes propagation of language-initialization results from the outer-most project into any number of try-compile levels.

No /fast targets in try_compile project mode The try_compile command builds the cmTryCompileExec executable using the cmTryCompileExec/fast target with Makefile generators in order to save time since dependencies are not needed. However, in project mode the command builds an entire source tree that may have dependencies. Therefore we can use the /fast target approach only in one-source mode.
