New in version 3.15.
Select the MSVC runtime library for use by compilers targeting the MSVC ABI.
The allowed values are:
-MTor equivalent flag(s) to use a multi-threaded statically-linked runtime library.
-MDor equivalent flag(s) to use a multi-threaded dynamically-linked runtime library.
-MTdor equivalent flag(s) to use a multi-threaded statically-linked runtime library.
-MDdor equivalent flag(s) to use a multi-threaded dynamically-linked runtime library.
The value is ignored on compilers not targeting the MSVC ABI, but an unsupported value will be rejected as an error when using a compiler targeting the MSVC ABI.
The value may also be the empty string (
"") in which case no runtime
library selection flag will be added explicitly by CMake. Note that with
Visual Studio Generators the native build system may choose to
add its own default runtime library selection flag.
generator expressions to
support per-configuration specification. For example, the code:
add_executable(foo foo.c) set_property(TARGET foo PROPERTY MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug>")
selects for the target
foo a multi-threaded statically-linked runtime
library with or without debug information depending on the configuration.
The property is initialized from the value of the
CMAKE_MSVC_RUNTIME_LIBRARY variable, if it is set.
If the property is not set, then CMake uses the default value
MultiThreaded$<$<CONFIG:Debug>:Debug>DLL to select a MSVC runtime library.
