It's fine to have it in a branch, but it shouldn't go to master. Current crypto3 uses ::all target

@AndreyMlashkin, are you sure?
I tried it with latest master and got an error:

CMake Error at libs/transpiler/CMakeLists.txt:47 (target_link_libraries):
  The link interface of target "crypto3_transpiler" contains:

    crypto3::all

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.
