build CMake

18.04 的 cmake 是 3.10.2
在 cuda version 大於 10.2(?) 之後，會出現 CUDA_cublas 找步道的問題。
所以要手動安裝 大於 3.14 的 cmake

那就從 source checkout 開始吧..

cmake 的 source 放在gitlab。下面剛好就是 build instruction..
目標是build 出執行檔，然後放在local (PATH 順序)

checkout 最新的 release v3.18，follow 說明，先 run bootstrap 看說明..

charles-chang@penguin1:~/githubgitlab/cmake$ ./bootstrap --help

  --qt-gui                build the Qt-based GUI (requires Qt >= 4.2)

Directory and file names:
  --prefix=PREFIX         install files in tree rooted at PREFIX
                          [/usr/local]
  --bindir=DIR            install binaries in PREFIX/DIR
                          [bin]
  --datadir=DIR           install data files in PREFIX/DIR

                          [man]
  --xdgdatadir=DIR        install XDG specific files in PREFIX/DIR

只有要改 install path 而已，所以...

$./bootstrap --prefix=/home/charles-chang/cmaketool
...
...
$ make
...
$ make install

寫一個 addcmake18path.sh:

#!/bin/bash
export CMAKE_ROOT=/home/charles-chang/cmaketool
export PATH="/home/charles-chang/cmaketool/bin:$PATH"

要用 3.18 舊先 source ..

其他

原來 Caffe 也有 cmake，source folder 有 CMakeList.txt
所以可以follow 標準..

mkdir build && cd build
cmake ..
make
