我想禁用Fieldset中的所有元素,但在其中启用了几个按钮. 演示:

<fieldset ng-disabled="true">
    <legend>Personalia:</legend>
    Name: <input type="text"><br>
    Email: <input type="text"><br>
    Date of birth: <input type="text">

    <input type="button" value="See More (Enable this!!) " ng-click="ButtonClicked1()" ng-disabled="false"/>
    Somethingelse: <input type="text">
    <input type="button" value="View Details " ng-click="ButtonClicked2()"/> 
</fieldset>

我正在按照本指南关于如何使用GLFW3和OSake 10.9.1上的CMake构建项目,我遇到了一些麻烦.当我构建实际项目时,我收到以下错误:
