Thanks for feedback : > IF (${ARMADILLO} STREQUAL “ARMADILLO-NOTFOUND”) > # do what you want > ENDIF () I tried this way of writing :
IF (${ARMADILLO} STREQUAL "ARMADILLO-NOTFOUND") include(ExternalProject) ExternalProject_Add(armadillo URL https://github.com/lsolanka/armadillo/archive/master.zip PREFIX ${CMAKE_CURRENT_BINARY_DIR}/armadillo-latest) ENDIF() and IF (ARMADILLO STREQUAL ARMADILLO-NOTFOUND) include(ExternalProject) MESSAGE(STATUS "Trying to install armadillo...") ExternalProject_Add(armadillo URL https://github.com/lsolanka/armadillo/archive/master.zip PREFIX ${CMAKE_CURRENT_BINARY_DIR}/armadillo-latest) ENDIF() But both of them gave me an error : -- * Armadillo Library location: ARMADILLO-NOTFOUND-- Trying to install armadillo...-- Sndfile Library location: SNDFILE-NOTFOUND-- Trying to install libsndfile...CMake Error: The following variables are used in this project, but they are set to NOTFOUND.Please set them or make sure they are set and tested correctly in the CMake files:ARMADILLO linked by target "tsm" in directory /home/computing9/TSM_cmakeSNDFILE linked by target "tsm" in directory /home/computing9/TSM_cmake-- Configuring incomplete, errors occurred!See also "/home/computing9/TSM_cmake/build/CMakeFiles/CMakeOutput.log".* ExternalProject_add command is not instlling the mentioned libraries from the specifies link .
