WATCOM_RUNTIME_LIBRARYΒΆ

Added in version 3.24.

Select the Watcom runtime library for use by compilers targeting the Watcom ABI.

The allowed values are:

SingleThreaded

Compile without additional flags to use a single-threaded statically-linked runtime library.

SingleThreadedDLL

Compile with -br or equivalent flag(s) to use a single-threaded dynamically-linked runtime library. This is not available for Linux targets.

MultiThreaded

Compile with -bm or equivalent flag(s) to use a multi-threaded statically-linked runtime library.

MultiThreadedDLL

Compile with -bm -br or equivalent flag(s) to use a multi-threaded dynamically-linked runtime library. This is not available for Linux targets.

The value is ignored on non-Watcom compilers but an unsupported value will be rejected as an error when using a compiler targeting the Watcom ABI.

The value may also be the empty string ("") in which case no runtime library selection flag will be added explicitly by CMake.

Use generator expressions to support per-configuration specification.

For example, the code:

add_executable(foo foo.c)
set_property(TARGET foo PROPERTY
  WATCOM_RUNTIME_LIBRARY "MultiThreaded")

selects for the target foo a multi-threaded statically-linked runtime library.

If this property is not set then CMake uses the default value MultiThreadedDLL on Windows and SingleThreaded on other platforms to select a Watcom runtime library.

Note

This property has effect only when policy CMP0136 is set to NEW prior to the first project() or enable_language() command that enables a language using a compiler targeting the Watcom ABI.
