CMake ctest helper

Hi!

The awesome feature, cmake helper, made my life easier to write some receipts, but when I need write some test_package conanfile, I have:

    cmake = None

    def build(self):
        self.cmake = CMake(self.settings)
        self.cmake.configure(self, source_dir=self.conanfile_directory, build_dir="./")
        self.cmake.build(self)

    def test(self):
        target_test = "RUN_TESTS" if self.settings.os == "Windows" else "test"
        self.cmake.build(self, target=target_test)

I use CTest for my unit tests, so, I put enable_testing and add_test in my cmake file, but I need select the target word by platform. Maybe, would be a better approach if I have:

    cmake = None

    def build(self):
        self.cmake = CMake(self.settings)
        self.cmake.configure(self, source_dir=self.conanfile_directory, build_dir="./")
        self.cmake.build(self)

    def test(self):
        self.cmake.test(self)

This helper will solve the target name by platform and call cmake.build.

Right, was merged in Conan 0.22.

By default, CMake apply test for Linux, or RUN_TESTS for Visual Studio, as target, when enable_testing() is present in CMakeFile.txt.
Here is the explanation: Testing_With_CTest

However, anyone can create a custom target instead to run CTest:

# CMakeLists.txt
add_executable(test-app main.cpp)
add_custom_target(run-all-tests
                  WORKING_DIRECTORY "${CMAKE_BINARY_DIR}/bin"
                  COMMAND test-app)
add_dependecies(run-all-tests test-app)                                

And run:

$ cmake --build . --target run-all-tests

In this case, the better choice is just use cmake.build(self, target="run-all-tests").

Great idea, I can implement this little point 😃
