readme.txt파일 내용중 설치부분 설명.

You can use the manual installation process as described in section 3.2, or the following CMake based automatic installation.  * Step 1:  If CMake is not already be present on your system, download it from http://www.cmake.org  On major Linux systems (such as Fedora, Ubuntu, Debian, etc), cmake is available as a pre-built package, though it may need to be explicitly installed (using a tool such as PackageKit, yum, rpm, apt, aptitude).  * Step 2:  If you have BLAS and/or LAPACK, install them before installing Armadillo. Under Mac OS X this is not necessary.   On Linux systems it is recommended that the following libraries are present: LAPACK, BLAS, ATLAS and Boost. LAPACK and BLAS are the most important. If you have ATLAS and Boost, it's also necessary to have the corresponding header files installed.  * Step 3:   Open a shell (command line), change into the directory that was created by unpacking the armadillo archive, and type the following commands:   cmake .   make   The full stop separated from "cmake" by a space is important. CMake will figure out what other libraries are currently installed and will modify Armadillo's configuration correspondingly. CMake will also generate a run-time armadillo library, which is a combined alias for all the relevant libraries present on your system (eg. BLAS, LAPACK and ATLAS).   If you need to re-run cmake, it's a good idea to first delete the "CMakeCache.txt" file (not "CMakeLists.txt").  * Step 4:   If you have access to root/administrator/superuser privileges, first enable the privileges (eg. through "su" or "sudo") and then type the following command:   make install   If you don't have root/administrator/superuser privileges, type the following command:   make install DESTDIR=my_usr_dir   where "my_usr_dir" is for storing C++ headers and library files. Make sure your C++ compiler is configured to use the sub-directories present within this directory.
