Modules
Within a Slicer build-tree, where are Slicer modules located?
Slicer module executables and libraries are located in your main Slicer build directory Slicer-Superbuild/Slicer-build. Refer to Directory Structure description for more details.

How to modify local version of external module
Some Slicer modules (such as OpenIGTLink and OpenIGTLinkIF) are built as External git projects by CMake scripts in the Slicer/SuperBuild directory. The SuperBuild process may refresh from the repository unexpectedly, overwriting any local changes. To avoid this, comment out the git settings in the appropriate external build file while making local edits. For example, in SuperBuild/External_OpenIGTLinkIF.cmake:
GIT_REPOSITORY "${git_protocol}://github.com/openigtlink/OpenIGTLinkIF.git"
GIT_TAG "f9b65b1ffd2992862025f3c6ec5fe30e6f5dd395"
SOURCE_DIR ${CMAKE_BINARY_DIR}/${proj}

How to call a CLI module from a C++ loadable module?
Discussion: http://slicer-devel.65872.n3.nabble.com/Calling-CLI-module-from-a-C-loadable-module-tt4031930.html
Example: vtkSlicerCropVolumeLogic.cxx#L318-351
How to call a CLI module from command-line?
Example:
Slicer.exe --launch CastScalarVolume input.mha output.mha
Notes for windows:
- Full name of the Slicer executable is required (Slicer.exe, not just Slicer)
- To get help on command-line arguments the CLI module supports, run:
Slicer.exe --launch CastScalarVolume 2>c:\SomeWriteAbleDirectory\usage.txt
