I am trying to install openbabel-2.4.1 in my centos 7 system. The the cmake command (cmake ..) gives information that wxWidgets and Eigen cannot be found:

Actually I have installed wxWidgets-3.1.2 and EIGEN3 and add their lib path to the LD_LIBRARY_PATH environment variable, but why they cannot be found by cmake? And how to solve the problem? Thank you in advance.

CMake does not find MPI for Fortran.
I am on Arch Linux with CMake 3.19.2.
I installed the openmpi (4.0.5-2) package and as stated here I also installed the gcc-fortran (10.2.0-4) package for fortran support.
I my CMake script in the line where MPI should be found:
find_package(MPI REQUIRED)
it tells me that it could not find MPI for Fortran:
-- Found MPI_C: /usr/lib/openmpi/libmpi.so (found version "3.1")
-- Found MPI_CXX: /usr/lib/openmpi/libmpi_cxx.so (found version "3.1")
-- Could NOT find MPI_Fortran (missing: MPI_Fortran_WORKS)
CMake Error at /usr/share/cmake-3.19/Modules/FindPackageHandleStandardArgs.cmake:218 (message):
Could NOT find MPI (missing: MPI_Fortran_FOUND) (found version "3.1")
Call Stack (most recent call first):
/usr/share/cmake-3.19/Modules/FindPackageHandleStandardArgs.cmake:582 (_FPHSA_FAILURE_MESSAGE)
/usr/share/cmake-3.19/Modules/FindMPI.cmake:1721 (find_package_handle_standard_args)
CMakeLists.txt:387 (find_package)
When installing openmpi it tells me that fortran support should be enabled:
(2/2) installing openmpi
Optional dependencies for openmpi
gcc-fortran: fortran support [installed]
There is a file /usr/lib/openmpi/libmpi_mpifh.so. Correct me if I am wrong but I think this should be the correct library file.
Thanks in advance for your help!
EDIT
I just tried to build a minimal example:
project(test)
cmake_minimum_required(VERSION 3.0)
enable_language(Fortran)
find_package(MPI REQUIRED)
With this it finds MPI_Fortran
-- Found MPI_Fortran: /usr/lib/openmpi/libmpi_usempif08.so (found version "3.1")
The CMakeLists.txt is a rather long and legacy one...
Seems that I have to find the solution on my own.
I solved the problem. As said in the edit of the answer this is legacy cmake and not written by myself.
My fortran skills are not too advanced so I do not know why this is used but the following line did break the finding process of the library:
set(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -heap-arrays 0")
If anyone falls into the same trap try to avoid this!
You need to use the COMPONENTS keyword on the find_package command, e.g.
find_package(MPI REQUIRED COMPONENTS Fortran)
Be sure you have Fortran enabled in your CMakeLists.txt either by enabling it in the project command, i.e.
project(name LANGUAGES Fortran)
or by calling
enable_language(Fortran)
prior to find_package.
I am trying to build the ceres-solver on linux using CMake's external project feature.
I have a specific version of Eigen that I built and the other dependencies are installed through my packet manager (BLAS, LAPACK and Suitesparse).
If I build Ceres-solver directly from source:
cmake -G Ninja -DEIGEN_INCLUDE_DIR='<path-to-eigen>' -DEIGEN_BUILD_DIR='<path-to-eigen-build>' ..
It automatically finds suitesparse and all its dependencies (BLAS, LAPACK, AMD, COLAMD, etc.) and it build with no problems.
Here is CMake output :
-- Detected Ceres version: 2.0.0 from <path>/ceres-solver/include/ceres/version.h

But If I build Ceres-solver as an external project, It does not find BLAS (the same BLAS that is automatically found when I build directly from source).
Is there a difference in behavior when building a library through ExternalProject_Add vs. building it separately by hand ? Can options & variables defined in my "master" project (the one calling ExternalProject_Add) leak to the external project (and if yes, how can I prevent that ?).
My call to ExternalProject_Add :
ExternalProject_Add(ceres-solver
PREFIX CeresSolver
BINARY_DIR ${CMAKE_CURRENT_BINARY_DIR}/ceres-solver
SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/ceres-solver
INSTALL_DIR ${DEFAULT_INSTALL_ROOT}/ceres-solver

ZLIB for Windows is a part of the GnuWin32 project (I'm not sure whether it is allowed to give links on SO). As I see, the CMakeLists.txt uses find_package to lookup the ZLIB library:
if (NOT ZLIB_FOUND)
find_package(ZLIB)
endif()
if (NOT ZLIB_FOUND)
message(WARNING "Not found zlib: skip TDLib, tdactor, tdnet, tddb")
return()
endif()
How the find_package command works is well described in the official documentation:
The command has two modes by which it searches for packages: “Module” mode and
“Config” mode. Module mode is available when the command is invoked with the
above reduced signature. CMake searches for a file called Find<package>.cmake
in the CMAKE_MODULE_PATH followed by the CMake installation. If the file is
found, it is read and processed by CMake. It is responsible for finding the
package, checking the version, and producing any needed messages. Many find-
modules provide limited or no support for versioning; check the module
documentation. If no module is found and the MODULE option is not given the
command proceeds to Config mode.
I've had a look into FindZLIB.cmake on my Windows machine. The module uses the following path: ZLIB_ROOT and the following registry keys:
"[HKEY_LOCAL_MACHINE\SOFTWARE\GnuWin32\Zlib;InstallPath]"
"$ENV{PROGRAMFILES}/zlib
So, as I understand, if you install GnuWin32 using the installer, the HKLM key will be written down into the registry and CMake will be able to find the path to ZLIB. If you wish to use just the zip-archive, the ZLIB_ROOT parameter must be correctly specified when you run CMake:
cmake -DZLIB_ROOT=<PATH-to-your-unpacked-zlib> -D.....
I am trying to create a CMAKE project that includes other third party projects (OGRE3D, CEGUI, etc) and my specific project (or projects). More specifically, I have a directory tree like this:
+ myMasterProject
-----+ OGRE3D_DEPENDENCIES
-----+ OGRE3D_CORE
-----+ CEGUI
-----+ myProject
If I build the libraries manually one by one in the right order everything works fine (even myProject). Every project has its own CMakeLists.txt file, and they almost all use the find_package function. For example, CEGUI needs to find OGRE for the OGRE renderer and returns an error if does not find it with find_package(OGRE REQUIRED). myProject needs both OGRE and CEGUI.
An important detail is that I would not modify the CMakeLists.txt files of the subprojects, as I import them as sub-projects using mercurial or svn (depends on their respective CVS), and I prefer to update them regularly, without modifications (I'm not expert enough to modify them).
Does anyone have an idea on how to get to this result? shall I define all the variables like "OGRE_FOUND", "Boost_FOUND", and their respective sub-variables ("OGRE_LIB", "OGRE_H_PATH" etc) manually in my masterProject/CMakeLists.txt file or is there a "smarter" or "cleaner" way to do it? In any case, these variables have to be defined somehow, because they are needed by the projects...
For the moment, myMasterProject/CMakeLists.txt contains only:
project(myMasterProject)
add_subdirectory("OGRE3D_DEPENDENCIES")
add_subdirectory("OGRE3D_CORE")
add_subdirectory("CEGUI")
add_subdirectory("myProject")
Here is the CMAKE output that I get:

DISCLAIMER: I am almost a newbie with CMAKE... Moreover, I know that similar questions have been already posted here, but I didn't find an answer that works...
Setting the variables for the find script yourself in the master project is a valid approach. It is a bit fragile in the sense that you rely on the respective projects not changing their find scripts, but otherwise this seems perfectly fine.
An alternative could be using CMake's ExternalProject functionality. With this approach, instead of building all dependencies from your master project, they get built during CMake configure time. The advantage here is that dependencies are built as if you would build them directly from the command line, so the effects described in your question are avoided. It also does not depend on any of the dependency's build system internals.
