Summary0015067: include does not find files in current directory if module path discovered through CMAKE_PREFIX_PATH
DescriptionSetup:

someprefix/share/mytest/cmake/MyTestConfig.cmake:

  include(somethingspecific)

---

someprefix/share/mytest/cmake/somethingspecific.cmake:

  message("Hello, World!")

---

somesourcecode/CMakeLists.txt

  cmake_minimum_required(VERSION 3.0)

  find_package(MyTest REQUIRED CONFIG)

---

Build with

cmake .. -DCMAKE_PREFIX_PATH=someprefix

CMake Error at (snip)/someprefix/share/mytest/cmake/MyTestConfig.cmake:1 (include):
  include could not find load file:

    somethingspecific
Call Stack (most recent call first):
  CMakeLists.txt:3 (find_package)


This is the setup LLVM has for its config, and it does not work in our setup for the same reason.

Manually adding someprefix/share/mytest/cmake to the CMAKE_MODULE_PATH fixes this, but is that not implied from someprefix being on the CMAKE_PREFIX_PATH?

Our scenario is that we have many isolated package installations distributed across many prefixes, each with an entry on CMAKE_PREFIX_PATH.

Thanks

 CMAKE_MODULE_PATH is the search path for include().
CMAKE_PREFIX_PATH is a search path for find_package() and related commands.

They are completely independent. Neither implies the other.

 LLVM 3.5 has improved support for CMake applications. When using LLVM 3.5 you can do something like:

 find_package(LLVM REQUIRED CONFIG)
 list(APPEND CMAKE_MODULE_PATH "${LLVM_CMAKE_DIR}")
 include(AddLLVM)

See

 http://llvm.org/docs/CMake.html#embedding-llvm-in-your-project [^]

(which has been updated recently).
