# Skip this step if Build_Deps option is set.

|
# ${CMAKE_SOURCE_DIR}/deps/name. If found
|
|
# build it as a cmake sub-project.

# and build them as a cmake sub-project.

# GIT_TAG - Use this keyword to specify the git-tag, branch or commit hash

# and will never be searched in the system.

# will not be included in the ALL target of the project.

# In particular the dependency will not be installed.
