gqcg / gqcp-link Goto Github PK

Having installed the latest develop branch from gqcp in /usr/local/ (the default settings), I'm building this project with

cmake .. -DCMAKE_PREFIX_PATH="/Users/laurentlemmens/miniconda/envs/gqcg_dev"

where Eigen/libcint/libint2/... are installed. I'm getting the following error:

CMake Error at /Users/laurentlemmens/miniconda/share/cmake-3.15/Modules/CMakeFindDependencyMacro.cmake:47 (find_package):
No "FindEigen3.cmake" found in CMAKE_MODULE_PATH.
Call Stack (most recent call first):
/usr/local/cmake/gqcp-config.cmake:29 (find_dependency)
CMakeLists.txt:8 (find_package)

CMake Warning (dev) at /Users/laurentlemmens/miniconda/share/cmake-3.15/Modules/CMakeFindDependencyMacro.cmake:47 (find_package):
FindEigen3.cmake must either be part of this project itself, in this case
adjust CMAKE_MODULE_PATH so that it points to the correct location inside
its source tree.

Or it must be installed by a package which has already been found via
find_package(). In this case make sure that package has indeed been found
and adjust CMAKE_MODULE_PATH to contain the location where that package has
installed FindEigen3.cmake. This must be a location provided by that
package. This error in general means that the buildsystem of this project
is relying on a Find-module without ensuring that it is actually available.

Call Stack (most recent call first):
/usr/local/cmake/gqcp-config.cmake:29 (find_dependency)
CMakeLists.txt:8 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.

@guacke Does this really mean we have to provide a CMAKE_MODULE_PATH in any down-stream library, or is the current gqcp CMake installation broken?
