Anyway, I have a new set of projects and my current problem is that i have
some code that i share between projects. Once source can be shared not
binaries.
Code is organized as;
src/common
src/project1
src/project2
The CMakeLists.tst files are located inside for each project which sets the
right compiler and sources to be built. Now i want common to be included in
each of these proejects and build separately for each by inheriting all the
settings for that project.
What is the best way to achieve this? I cant use ADD_SUBDIRECTORY() as it
is really a sibling folder (cmake complains if I use "../common").
Does anybody have a solution around this? The only way i could think of is to
copy the common folder during configure time and run cmake again inside it by
using the current cache. This is not a very efficient way as not all of the
common folder code is necessary in every project. Also code changes in the
common directory will not result in an update in the project.
Have a look at LOAD_CACHE in the documentation. This will allow you to
load in cache variables from another cmake build.
Also look at EXPORT_LIBRARY_DEPENDENCIES if you need to get out library
dependencies of your project. With that file you can simply IMPORT()
said file in your new project and life gets happy again. I've done this
with projects that build static libraries, and I need to tell an
external project the library dependencies.
