Using a classical Makefile

There are two ways to integrate ViSP as a 3rd-party in a Makefile:

either using pkg-config over visp.pc file that you may find in ViSP installation folder; typically in /usr/local/lib/pkgconfig folder,
either using visp-config shell script file that you may find in ViSP build folder; typically in $VISP_WS/visp-build/bin folder.

Using pkg_config

To get compiler flags use:
```
$ pkg-config --cflags visp
```
To get linker flags use:
```
$ pkg-config --libs visp
```

Note

If visp.pc file used by pkg-config is not found, you may set PKG_CONFIG_PATH environment variable with the path to access to visp.pc using a command similar to:

$ export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:<visp install tree>/lib/pkgconfig

To build a file named HelloWorld.cpp, both command could be used in a Makefile which content would be the following:

CXX            = g++
VISP_CFLAGS    = `pkg-config --cflags visp`
VISP_LDFLAGS   = `pkg-config --libs visp`

HelloWorld: HelloWorld.cpp
    $(CXX) $(VISP_CFLAGS) -o HelloWorld HelloWorld.cpp $(VISP_LDFLAGS)

clean:
    rm -f *~ HelloWorld

Using visp-config

To get compiler flags use:

$ cd $VISP_WS/visp-build
$ visp-config --cflags visp

To get linker flags use:
```
$ visp-config --libs visp
```

To build a file named HelloWorld.cpp, both command could be used in a Makefile which content would be the following:

CXX            = g++
VISP_BUILD_DIR = ${VISP_WS}/visp-build
VISP_CFLAGS    = `$(VISP_BUILD_DIR)/bin/visp-config --cflags`
VISP_LDFLAGS   = `$(VISP_BUILD_DIR)/bin/visp-config --libs

HelloWorld: HelloWorld.cpp
    $(CXX) $(VISP_CFLAGS) -o HelloWorld HelloWorld.cpp $(VISP_LDFLAGS)

clean:
    rm -f *~ HelloWorld
