Use case: build already downloaded superbuild without network connection
Probably related to https://github.com/robotology/ycm/issues/58 , but I open the issue to state the user case clearly.
If the user has an already downloaded superbuild repository, and wants to compile it off-line, the make or make subproject commands fail with the following error:
-- YCM not found. Bootstrapping it.
-- Downloading YCMEPHelper.cmake
-- Downloading YCMEPHelper.cmake - ERROR 6: "Couldn't resolve host name"
CMake Error at cmake/YCMBootstrap.cmake:87 (ycm_bootstrap):
Unknown CMake command "ycm_bootstrap".
Call Stack (most recent call first):
CMakeLists.txt:27 (include)
A typical example of this use case is if someone is programming while commuting on a train.
A workaround that I found is to call make and make install in all the build directories of the modifed subprojects. Another workaround is to use a installed YCM instead of a bootstrapped one.
About installing YCM, you have to be careful of installing it again each time it gets updated. If using YCM inside a superbuild, it means that each time you do an update of the whole superbuild 'someone' should check if the YCM has changed and install it again.
