QMake alternative of cmake's “find_package”?

aravmadd

HI,

Currently i am using eigen library for one of my project.

In CMake I can simply specifiy like

find_package(Eigen3 CONFIGREQUIREDHINTS${CMAKE_SOURCE_DIR}/libs/eigen/share/eigen3/cmake)

However in Qmake i need to specify like

INCLUDEPATH += ..\dependencies\eigen\include\eigen3\Eigen

By doing like mentioned above in pro file the problem is in my source codes i need to mention like below which are local paths and i dont like to use local paths so that it wont be a problem if i give this code to someone.

#include <C:\Users\aravmadd\Desktop\project_qt\libs\eigen\include\eigen3\Eigen\Dense>

However if i use find_package like CMake, i can just use like #include "Eigen\Dense"  in  the source codes

Can you please suggest some alternatives so that i can replace that above local include path to simply like #include "Eigen\Dense"

For Example if i mentioned in qmake

INCLUDEPATH += ..\libs\eigen\include\eigen3\Eigen

LIBS += -lwsock32
LIBS += -lws2_32
LIBS +=  -lkernel32 -lkernel32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lodbc32 -lodbccp32

then i can use eigen library like this in my source codes

However if i use cmake like this

find_package(Eigen3 CONFIGREQUIREDHINTS${CMAKE_SOURCE_DIR}/libs/eigen/share/eigen3/cmake)

target_link_libraries(project PRIVATE Qt${QT_VERSION_MAJOR}::Core Qt${QT_VERSION_MAJOR}::Widgets Qt${QT_VERSION_MAJOR}::Concurrent  wsock32 ws2_32 Eigen3::Eigen)

then i can use eigen functionalites like this in my source code.

@aravmadd said in QMake alternative of cmake's “find_package”?:

INCLUDEPATH += ..\libs\eigen\include\eigen3\Eigen

If you do this:

INCLUDEPATH += ../libs/eigen/include/eigen3

It will allow you to use nice includes:

#include "Eigen/Dense"
#include "Eigen/Geometry"

Regarding your main question - there is nothing like find_package() in qmake. That's one of the reasons why Qt is moving away from qmake :-)

There is stuff like inclusion of .pri files, or even .prf, but it does not compare to find_package() at all.

@sierdzio Thanks for the quick reply.

I tried with cmake it is working great, but only problem is when i run the executable and generate all the dlls required using windeployqt.exe then for some reasons along with gui there is one thing like cmd shell is also opening :-(. Instead of trying to find this i thought i will find some alternative for find_package in qmake

What i did was i have a folder called 3rd_Party.It only contains CMakeLists.txt file. And this CMakeList file builds the eigen library and creates one folder libs.And inside libs folder i can find all the required things. So basically now my build procedure is of two steps. First step is to build eigen thing using CMakelists.txt and second step was building qt project using qmake in QtCreator

And you go to all that trouble just because a terminal window is showing up? You should rather fix the root cause of that instead of investing time in workarounds! And it is easy to do:

add_executable(projectName WIN32 main.cpp)

This WIN32 should be enough to stop terminal from showing up.
