- update to CMake 3.6.0
* The “list()” command gained a “FILTER” sub-command to filter
list elements by regular expression.
* A “CMAKE_TRY_COMPILE_TARGET_TYPE” variable was added to optionally
tell the “try_compile()” command to build a static library instead
of an executable.
* A “_CLANG_TIDY” target property and supporting
“CMAKE__CLANG_TIDY” variable were introduced to tell the
Makefile Generators and the “Ninja” generator to run “clang-tidy”
along with the compiler for “C” and “CXX” languages.
* The “ExternalProject” module leared the “GIT_SHALLOW 1” option to
perform a shallow clone of a Git repository.
* The “ExternalProject” module learned to initialize Git submodules
recursively and also to initialize new submodules on updates.
* The “InstallRequiredSystemLibraries” module learned a new
“CMAKE_INSTALL_UCRT_LIBRARIES” option to enable app-local deployment
of the Windows Universal CRT libraries with Visual Studio 2015.
* The “Compile Features” functionality is now aware of features
supported by Intel C++ compilers versions 12.1 through 16.0 on UNIX
platforms.
* The “CMakeForceCompiler” module and its macros are now deprecated.
