Qt Creator：包含库时出错“跳过不兼容”

Question

我在Linux KDE上使用Qt Creator。我即将在我的Qt项目中包含一个库。该库已成功包含，但我收到以下错误：

    :-1: error: skipping incompatible /home/administrator/yyyyy/xxxxx/../../../../opt/QtSDK
/Madde/sysroots/harmattan-nokia-meego-arm-sysroot-1122-slim/usr/lib//libcrypto.so when 
searching for -lcrypto (the following is in red colour) File not found: (which one isn't 
told)

我使用Qt Creator中的“添加库”功能在.pro文件中添加了库，并选择了“外部库”。我得到了以下代码：

unix:!macx:!symbian: LIBS += -L$$PWD/../../../../opt/QtSDK/Madde/sysroots/harmattan-nokia-meego-arm-sysroot-1122-slim/usr/lib/ -lcrypto

INCLUDEPATH += $$PWD/../../../../opt/QtSDK/Madde/sysroots/harmattan-nokia-meego-arm-sysroot-1122-slim/usr/include/openssl
DEPENDPATH += $$PWD/../../../../opt/QtSDK/Madde/sysroots/harmattan-nokia-meego-arm-sysroot-1122-slim/usr/include/openssl

unix:!macx:!symbian: PRE_TARGETDEPS += $$PWD/../../../../opt/QtSDK/Madde/sysroots/harmattan-nokia-meego-arm-sysroot-1122-slim/usr/lib/libcrypto.a

其实我的程序有效，但我不明白Qt在做什么。似乎Qt试图包含其他具有相似名称的库 - 但为什么呢？

可能是您的系统上同时拥有x64和x86库，并且在查找过程中会跳过不兼容的库
