Support multiple install dirs for built/custom targets You can now pass a list of strings to the install_dir: kwarg to build_target and custom_target. Custom Targets: =============== Allows you to specify the installation directory for each corresponding output. For example: custom_target('different-install-dirs', output : ['first.file', 'second.file'], ... install : true, install_dir : ['somedir', 'otherdir]) This would install first.file to somedir and second.file to otherdir. If only one install_dir is provided, all outputs are installed there (same behaviour as before). To only install some outputs, pass `false` for the outputs that you don't want installed. For example: custom_target('only-install-second', output : ['first.file', 'second.file'], ... install : true, install_dir : [false, 'otherdir]) This would install second.file to otherdir and not install first.file. Build Targets: ============== With build_target() (which includes executable(), library(), etc), usually there is only one primary output. However some types of targets have multiple outputs. For example, while generating Vala libraries, valac also generates a header and a .vapi file both of which often need to be installed. This allows you to specify installation directories for those too. # This will only install the library (same as before) shared_library('somevalalib', 'somesource.vala', ... install : true) # This will install the library, the header, and the vapi into the # respective directories shared_library('somevalalib', 'somesource.vala', ... install : true, install_dir : ['libdir', 'incdir', 'vapidir']) # This will install the library into the default libdir and # everything else into the specified directories shared_library('somevalalib', 'somesource.vala', ... install : true, install_dir : [true, 'incdir', 'vapidir']) # This will NOT install the library, and will install everything # else into the specified directories shared_library('somevalalib', 'somesource.vala', ... install : true, install_dir : [false, 'incdir', 'vapidir']) true/false can also be used for secondary outputs in the same way. Valac can also generate a GIR file for libraries when the `vala_gir:` keyword argument is passed to library(). In that case, `install_dir:` must be given a list with four elements, one for each output. Includes tests for all these.
