GNUtoMS — CMake 3.31.6 Documentation

# GNUtoMS

Convert GNU import library (`.dll.a`) to MS format (`.lib`).

When linking a shared library or executable that exports symbols using GNU tools on Windows (MinGW/MSYS) with Visual Studio installed convert the import library (`.dll.a`) from GNU to MS format (`.lib`). Both import libraries will be installed by `install(TARGETS)` and exported by `install(EXPORT)` and `export()` to be linked by applications with either GNU- or MS-compatible tools.

If the variable `CMAKE_GNUtoMS` is set when a target is created its value is used to initialize this property. The variable must be set prior to the first command that enables a language such as `project()` or `enable_language()`. CMake provides the variable as an option to the user automatically when configuring on Windows with GNU tools.
