如何將glfw構建爲共享庫？

Question

我想在Linux上構建一個共享庫的glfw庫。我已經開始克隆git repository。然後，根據this編譯指南，我在回購庫中創建了一個名爲glfw-build的文件夾，並在其中創建了一個名爲cd的文件夾。 Runnnig cmake ..從那裏給人的輸出

我似乎得到的是一個一個文件，即靜態庫，但如前所述，我需要一個共享庫，即so-file。

爲什麼我不能得到這樣的文件;應該不是默認的？我怎麼能得到這個？

Answer 1

有些項目（其中glfw3）隱含允許用戶影響到圖書館的類型，他們通過BUILD_SHARED_LIBS變量產生：

如果存在和真實，這將導致所有庫要建共享，除非圖書館是明確添加爲一個靜態庫。這個變量通常作爲OPTION添加到項目中，以便項目的每個用戶都可以決定是使用共享庫還是靜態庫來構建項目。

與

cmake -DBUILD_SHARED_LIBS=ON .. 

配置告訴項目生成共享庫。

請注意，如果要在系統中同時存在兩種類型的庫，則需要爲它們指定不同的安裝前綴（CMAKE_INSTALL_PREFIX變量）。

並非所有項目都允許進行此類調整。有些項目自己選擇構建類型。一些其他人爲此使用另一個變量。只需閱讀項目的自述文件或檢查其代碼。
