cppmm-build

Build script utlities for binding projects created with cppmm

Example build.rs

When placed in the build.rs for openexr-sys this will build the cppmm-generated C wrapper libraries, including filling in platform-specific ABI information.

Packaged dependencies are assumed to live in thirdparty/<dependency> and the listed ones will be built and linked against. Users wishing to build against system libraries should set the CMAKE_PREFIX_PATH environment variable.

If the CMAKE_PREFIX_PATH environment variable is set, but you wish to build the pacakged depdencies anyway, set CPPMM_OPENEXR_BUILD_LIBRARIES=1.

If you wish to control the CMake build type, set e.g. CPPMM_OPENEXR_BUILD_TYPE=Debug (default is "Release").

use cppmm_build::{build, Dependency};

fn main() {
    build(
        // project name controls the name of the built C libraries as well as the names
        // of the _BUILD_LIBRARIES and _BUILD_TYPE environment variables
        "openexr",
        // project major version
        0,
        // project minor version
        10,
        // list of dependencies that are packaged with the crate and should be built
        // when `CMAKE_PREFIX_PATH` is not set, or `CPPMM_OPENEXR_BUILD_LIBRARIES` is
        // set to 1
