New in version 3.15.
Select the MSVC runtime library for use by compilers targeting the MSVC ABI.
This variable is used to initialize the
property on all targets as they are created. It is also propagated by
calls to the
try_compile() command into the test project.
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:
selects for all following targets a multi-threaded statically-linked runtime library with or without debug information depending on the configuration.
If this variable is not set then the
property will not be set automatically. If that property is not set then
CMake uses the default value
to select a MSVC runtime library.
