I’m trying to build the most recent version of OpenCV on a minimal enough VPS but am running into trouble with CMake. I’m not familiar with CMake so I’m finding it difficult to interpret the log output and thus how to proceed to debug the problem.
From the command line (x11 isn’t installed) and within devel/OpenCV/-2.3.1/release I issue the following
sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
and the result of this is the following:

Also when I run the command I also seem to be getting the following error message
CMake Error at CMakeLists.txt:44 (set_property):
set_property given invalid scope CACHE. Valid scopes are GLOBAL,
DIRECTORY, TARGET, SOURCE, TEST.
Line 42-45 is the following:
set(CMAKE_CONFIGURATION_TYPES "Debug;Release" CACHE STRING "Configs" FORCE)
if(DEFINED CMAKE_BUILD_TYPE)
set_property( CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS ${CMAKE_CONFIGURATION_TYPES} )
endif()
However I’m not sure what this means? Does aNyone have any pointers?
Many thanks
Check your CMake version. Support for
set_property(CACHE ... )was implemented in 2.8.0.If upgrading CMake is not an option for you – I guess it’s safe to comment line #44. It seems to be used to create values for drop-down list in GUI.
