QMAKE找到庫指定的文件夾中的鏈接但沒有

我想在QVTKWidget在qmake的Qt 5.7的項目整合，從而提供我的應用程序與3D一些不錯的支持曲面圖（2D圖表特徵目前由Qwt處理，但如果我覺得它足夠容易集成，我可能會切換到VTK的2D圖表模塊）。

什麼已經做了迄今爲止

我已經成功地構建了VTK工具包的調試和在C:\VTK和C:\VTKDebug\發行版本（分別可用。此外，我也已經成功地設法將一些在我的QWidget VTK含量手動指定其中DLL庫是被包括在內。

問題

標題中提到的問題出現在我使用qmake的函數files()從C:\VTK\bin或C:\VTKDebug\bin取回所有共享庫時，取決於項目的構建類型。原因在於，根據我在應用程序中包含的內容，我可能需要手動指定3-4個或20-30個VTK庫。爲了創建一個原型，這是相當的體力勞動，我想稍後跳過該部分，然後在評估VTK是否適合我的需求之後處理它。 VTK提供的cmake模塊提供此功能，所以如果您願意，您可以簡單地鏈接到${VTK_LIBRARIES}。目前我不知道qmake項目的開箱即用支持。

到目前爲止，這麼好。如前所述事情不能在鏈接階段即出現以下錯誤

cannot find -lvtkalg-7.0 cannot find -lvtkxml2-7.0 cannot find -lvtkz-7.0

即使我可以清楚地看到他們在輸出qmake：

Project MESSAGE: Appending -LC:\Qwt-6.1.3\lib -lqwtd -LC:\Program Files (x86)\Device\api\lib -ldevice_apid -LC:\VTKDebug\bin -lvtkalg-7.0 ... -lvtkxml2-7.0 .. -lvtkz-7.0

我懷疑，這實際上有什麼關係與VTK本身，而是與我的項目的結構。

編輯：我已經找到了原因，但不知道如何解決它。基本上提到的文件有命名傳送libvtkNAMElib-7.0。所以當我做$$replace(BASENAME, lib,)都lib子串被刪除，離開我vtkNAME-7.0這不存在。我在資源管理器中查看上述DLL文件時發現了這一點，並注意到這種麻煩。我現在正在尋找一種方法來替換子字符串的第一次出現。

PS：我很不高興VTK工具包是如何管理文件結構的。對於開發人員來說，庫文件的命名約定似乎並不重要（本評論沒有任何意圖）。： -/

好的，問題解決了。正如我在EDIT部分中提到的那樣，問題在於VTK開發人員選擇的奇怪命名約定，以及三個（至少在我的版本中未啓用所有功能的情況下）這些事實圖書館不符合其餘的。

造成該問題的庫

libvtkalglib-7.0 
libvtkxml2lib-7.0 
libvtkzlib-7.0

，其餘遵循命名架構

libvtkXXX-7.0

我的一位同事注意到，所有文件都以libvtk*並不僅僅是lib的圖案。如果編輯replace()我正則表達式模式

NO_PREFIX_NAME = $$replace(BASENAME, libvtk, vtk)

我得到期望的結果，因爲只有lib還涵蓋*lib*而libvtk涵蓋*libvtk*這意味着*lib-7.0不落入了比賽。

這是爲那些誰想要它最終的DLL文件抓住循環：

LIBS += -L$$VTK_API\\bin 
VTK_API_SHARED_LIB_FILES = $$files($$VTK_API\\bin\\*.dll) 
for(FILE, VTK_API_SHARED_LIB_FILES) { 
    BASENAME = $$basename(FILE) 
    NO_PREFIX_NAME = $$replace(BASENAME, libvtk, vtk) # 3 of the VTK libs have the naming convention libvtkXXXlib-7.0 instead of libvtkXXX-7.0 
    VTK_LIB = $$replace(NO_PREFIX_NAME, .dll,) 
    message(Found "$$VTK_LIB") 
    LIBS += -l$$VTK_LIB 
}
