花了一天時(shí)間終于大功告成了，主要事件都花在下載opencv的開(kāi)源代碼上了，雖然不大（也就80多M），但是網(wǎng)速炸啊。十幾二十幾K的下，開(kāi)了vpn都沒(méi)用，一樣是龜速。言歸正傳
要準(zhǔn)備三樣?xùn)|西，一個(gè)是QT的開(kāi)源代碼（注意是源碼，不是什么安裝包），一個(gè)是CMake，還有一個(gè)就是opencv啦。具體的鏈接自己去官網(wǎng)找吧。。。我用的是qt5.5.1，CMake最新版，opencv2.4.11（因?yàn)樽钚碌膐pencv我編譯的時(shí)候總是出錯(cuò)，只好用opencv2了）
首先要把QT裝好，然后配置好環(huán)境變量Path，這也不細(xì)說(shuō)。接下來(lái)安裝CMake，注意勾選將XXX加入環(huán)境變量。裝好CMake后就可以開(kāi)始安裝opencv啦。先把下好的opencv源碼解壓好，打開(kāi)CMake，在源路徑中填上源碼的路徑，在目標(biāo)路徑中填上你想安裝的路徑（最好是你要安裝的位置，見(jiàn)一個(gè)build文件夾）不用源碼安裝的話，目錄下最終會(huì)生成build，source文件夾，分別存放待編譯的文件和源碼。
點(diǎn)擊configure，然后選WINGW Makefile 和下面第二個(gè)選項(xiàng)，然后c和c++的編譯器要到QT的安裝目錄的mingw里面找。等待。然后勾上WITH_QT,WITH_OPENGL;在次點(diǎn)擊configure（重要！）。然后generate；
進(jìn)入cmd，找到相應(yīng)目錄，mingw32-make 漫長(zhǎng)的等待。。。。? ?mingw32-make install
安裝成功，接下來(lái)就是配置。
