You can export a project as a set of files and a makefile to build the application. The makefiles generated by the IDE are compatible with both nmake and gmake.
Right-click any project and select Export to makefile.
You can now select the project (or projects) that you wish to be exported and the folder into which the data are to be written. Each selected project appears in a sub-folder with the same name as the project.
To build a project from the exported data, execute the makefile in the relevant folder. The application file is created in a sub-folder called output. There is also a make clean option to delete files created by the make process.
