Qt编译前自动执行和编译后自动执行脚本

引用：https://blog.csdn.net/wkr2005/article/details/93711321

qt的pro配置文件中也可添加各种编译前后的操作及配置，主要通过 QMAKE_POST_LINK和QMAKE_PRE_LINK；

QMAKE_POST_LINK表示编译后执行内容

QMAKE_PRE_LINK表示编译前执行内容

举例如下：

#-------------------------------------------------
#
# Project created by QtCreator 2020-11-13T10:30:08
#
#-------------------------------------------------
QT -= gui
TARGET = ComuPCIe
TEMPLATE = lib
DEFINES += COMUPCIE_LIBRARY
# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS
# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0
DESTDIR += ../bin
SOURCES += \
comupcie.cpp
HEADERS += \
comupcie.h
unix {
target.path = /usr/lib
INSTALLS += target
}
win32 {
binDstPath = C:/radsim/bin
libDstPath = C:/radsim/lib
headerDstPath = "C:\\radsim\\include\\"
libSrcName = $$DESTDIR/*.lib
binSrcName = $$DESTDIR/*.dll
headerSrcName = $$PWD/comupcie.h
exists($$headerSrcName){
message($$headerSrcName)
message($$headerDstPath)
message($$replace(headerSrcName, /, \\))
}
QMAKE_POST_LINK += copy /Y $$replace(headerSrcName, /, \\) $$headerDstPath
}

就是说， QMAKE_POST_LINK 后面可以追加要执行的命令，这些命令必须可以再命令行运行，当然，这就运行你写脚本了。

补充：

在windows系统下面，由于命令行中大部分命令不支持“/”，所以把“/”替换成“\”。

多条命令语句之间可以用&&隔开，自动连续执行；

定义的宏变量，在非首位置使用时，需要带{}， 如

PWD/">PWD/

PWD/{DESTDIR}/$${TARGET}.dll中的DESTDIR和TARGET。
